ABSTRACT

A controller outputs an image of the virtual space in correspondence with a posture of a first user wearing the mounted display, outputs an image of the virtual space to a touch panel display used by a second user, performs a first action in the virtual space in correspondence with a touch operation performed by the second user on the touch panel display, outputs an image of the virtual space reflecting the first action to the mounted display, and performs a second action in the virtual space reflecting the first action in correspondence with an operation performed by the first user on an operation unit.

TECHNICAL FIELD

The present application relates to an application control program, anapplication control method, and an application control system that allowa plurality of users to share virtual space.

BACKGROUND

When a virtual reality game is played, an image of virtual space isdisplayed on a mounted display worn on the head of a user (hereinafterreferred to as head-mounted display (HMD)). The HMD includes a trackingsensor such as a gyro sensor and can detect motion of the head of theuser. When the user moves the head, the HMD changes the image to bedisplayed on the display so that the image follows the motion of thehead. In this manner, when the image of the game follows the motion ofthe head, the user can further concentrate on the game. That is, thesense of immersion in the game is increased.

Further, a game played by multiple users has also been proposed as oneof the virtual reality games described above. Patent document 1describes a game played by multiple users wearing HMDs. In this game,the position information of each user wearing the HMD is reflected onthe position information of an avatar in virtual space to render theavatar of each user in the virtual space.

SUMMARY Problems That are to be Solved

When multiple users play a virtual reality game, there may not be enoughHMDs for all of the users to play the game. In addition, there may be auser who does not want to wear the HMD. In this manner, varioussituations can be expected. However, there appears to be no game inwhich a user who is wearing the HMD and a user who is not wearing theHMD can both participate and contribution to an application by the userwho is not wearing the HMD can be increased.

It is an object of the present application to provide an applicationcontrol program, an application control method, and an applicationcontrol system in which a user who is wearing a mounted display and auser who is not wearing a mounted display can cooperate to play invirtual space.

DETAILED DESCRIPTION OF THE DRAWINGS First Embodiment

One embodiment of an application control program, an application controlmethod, and an application control system will now be described withreference to FIGS. 1 to 10. In the present embodiment, it is assumedthat a game application is provided as an application in which virtualspace is shared by multiple users.

As shown in FIG. 1, the application control system includes ahead-mounted display (hereinafter referred to as HMD) 11 serving as amounted display, an operation unit (controller) 14, a main display 12,and a touch panel display 13. The HMD 11 is worn on the head of a firstuser 101. The HMD 11 displays an image of the virtual space. The firstuser 101 searches for an object moving in the virtual space (hereinafterreferred to as moving object) and performs an action (second action) onthe found moving object by operating the operation unit 14. In thepresent embodiment, the first user 101 searches for a moving object suchas a “ghost” and shoots the moving object by on-operating the operationunit 14.

Images output to the main display 12 and the touch panel display 13 arevisually recognized by a second user 102. The second user 102 operatesthe touch panel display 13 to assist the first user 101 while visuallyrecognizing the images output to the main display 12 and the touch paneldisplay 13. The second user 102 may be able to inform the first user 101of the position of a moving object via an unamplified voice or voiceinput to a microphone.

The schematic configuration of the application control system 10 willnow be described with reference to FIG. 2. The application controlsystem 10 includes the HMD 11, the operation unit 14, the main display12, the touch panel display 13, and a control device 15 connected tothese components.

The HMD 11 includes an HMD controller 30, a tracking sensor 31, and adisplay 32. The HMD controller 30 outputs a signal corresponding to adetection result of the tracking sensor 31 to the control device 15 andreceives various signals such as an image signal input from the controldevice 15. The tracking sensor 31 is a sensor that determines anattention point of the first user 101 and detects, for example, theposition and orientation of the head of the first user 101. The trackingsensor 31 includes, for example, at least one of a gyro sensor, anacceleration sensor, and a geomagnetic sensor. As another embodiment, asensor that directly detects the eye motion of the first user 101, forexample, a sight line detection sensor, which emits near-infrared raysto an iris and detects its reflected light, may be used as the trackingsensor 31. The display 32 of the HMD 11 displays an image of apredetermined range of the virtual space centered about the attentionpoint of the first user 101. That is, the image of the predeterminedrange is displayed to be visually recognized by the first user 101. Theimage of the virtual space output to the display 32 of the HMD 11 ishereinafter referred to as the “first virtual space image.”

The operation unit 14 includes, for example, an operation button and anoperation lever and is configured to be operable without the first user101 looking at the operation unit 14. The operation unit 14 includes anacceleration sensor or the like and can detect, for example, a change ina direction from an initial position and the amount of the change. Theoperation unit 14 outputs, to the control device 15, a signal indicatingan on/off-operation by the second user 102, the change amount in thedirection of the operation unit 14, and the like.

The main display 12 is a display that can be visually recognized by thesecond user 102. The main display 12 displays the first virtual spaceimage in synchronization with the display 32 of the HMD 11.

The touch panel display 13 may be a touch panel display arranged on ahousing or a mobile information terminal such as a tablet or asmartphone. An image of projection of a part in the virtual space(hereinafter referred to as the second virtual space image) is output tothe touch panel display 13. In the present embodiment, an image(bird's-eye view image) taken by viewing the inside of the virtual spacefrom a viewpoint set at a position located upward in the verticaldirection from the first user 101 is used as the second virtual spaceimage. The initial view of the second virtual space image, which isdisplayed on the touch panel display 13 when a game is started, is takenfrom a viewpoint at a position that is the same as the position of thevirtual space projected on the first virtual space image, which isdisplayed on the display 32 of the HMD 11. The viewpoint position of thesecond virtual space image in the initial view may be the same as ordifferent from the viewpoint position of the first virtual space imagein the initial view. The position where the virtual space is projectedon the second virtual space image is varied and designated incorrespondence with a predetermined touch operation such as a swipeoperation performed by the second user 102. For example, the swipeoperation performed by the second user 102 varies the projection rangeof the virtual space to change the second virtual space image, and, whenthe swipe operation is stopped, it stops varying the projection range ofthe virtual space and designates the display range of the second virtualspace image. The “touch operation” includes, for example, a tapoperation, a swipe operation, a flick operation, a pinch-in operation, apinch-out operation, and a touch-and-hold operation. Further, the touchpanel display 13 outputs a signal corresponding to a touch operationperformed by the second user 102 to the control device 15. For example,the touch panel display 13 outputs a signal corresponding to the path ofa swipe operation, a signal corresponding to a contact position, and thelike.

The first virtual space image output to the display 32 of the HMD 11 andthe second virtual space image output to the touch panel display 13 areimages in the same virtual space. However, the first virtual space imagediffers from the second virtual space image in that the display range ofthe virtual space is varied in correspondence with the posture of thefirst user 101 in the first virtual space image, whereas the displayrange of the virtual space is varied in correspondence with a touchoperation performed by the second user 102 in the second virtual spaceimage. In addition, the touch panel display 13 displays a bird's-eyeview image that is a bird's-eye view of the virtual space taken from apredetermined position.

The control device 15 obtains signals output from the HMD 11, theoperation unit 14, and the touch panel display 13 and manages progressof the game made in the virtual space by the first user 101 and thesecond user 102.

The control device 15 includes a controller 16, a memory 17, and animage information memory 25. The controller 16 includes a calculator, avolatile memory, and a non-volatile memory and executes the game inaccordance with the application control program recorded in thenon-volatile memory. The memory 17 is an image processing memory and maybe a volatile memory or a non-volatile memory. The memory 17 recordsgame management information 18, attention point information 19,designated display range information 20, object position information 21,and contact position information 22.

The game management information 18 includes, for example, user ID andgame progress state and is updated as the game progresses. The attentionpoint information 19 is information of the position and orientation ofthe head of the first user 101 detected by the tracking sensor 31 orinformation indicating the position of the attention point identifiedfrom the position and orientation of the head. The attention pointinformation 19 is updated with the position and orientation of the headof the first user 101. The designated display range information 20indicates the range displayed on the touch panel display 13 through atouch operation performed by the second user 102 and is updated with thetouch operation performed by the second user 102. The object positioninformation 21 indicates the positions of moving objects that move inthe virtual space. The controller 16 randomly moves each moving objectin accordance with the application control program. The object positioninformation 21 is updated as the position of each moving object changes.For a moving object, the position in the first virtual space imageoutput to the HMD 11 and the main display 12 is synchronized with theposition in the second virtual space image output to the touch paneldisplay 13. In addition, the contact position information 22 indicatesthe contact position on the screen of the touch panel display 13 and isupdated with each touch operation performed by the second user 102.Further, the image information memory 25 records information that isused to render an image of the virtual space.

The controller 16 records, in the memory 17, the attention pointinformation 19 based on a signal input from the HMD 11. Further, thecontroller 16 records, in the memory 17 as the designated display rangeinformation 20, a signal corresponding to the designated display rangeinput from the touch panel display 13.

From the image information recorded in the image information memory 25,the controller 16 obtains image information of a predetermined rangecentered about the attention point based on the attention pointinformation 19 and outputs the obtained image information to the HMD 11and the main display 12 as the first virtual space image. Further, thecontroller 16 records, in the memory 17, a designated display rangedesignated by a touch operation performed by the second user 102 as thedesignated display range information 20. The controller 16 obtains imageinformation from the image information memory 25 based on the designateddisplay range information 20 and outputs the obtained image informationto the touch panel display 13 as the second virtual space image.Additionally, the controller 16 outputs a bird's-eye view image that isa bird's-eye view of part of or all of the virtual space to the touchpanel display 13.

The virtual space and the first virtual space image, which is output tothe HMD 11 and the main display 12, will now be described with referenceto FIG. 3. The HMD controller 30 determines the position and orientationof the head of the first user 101. For example, using the initialposition as a reference, the position and orientation of the head arecalculated as positions in three axial directions and angles about thethree axes, namely, an X-axis extending in the horizontal direction, apitch θp indicating the rotation direction about the X-axis, a Y-axisextending in the vertical direction, a yaw θy indicating the rotationdirection about the Y-axis, a Z-axis extending in the forward direction,and a roll θr indicating the rotation direction about the Z-axis. TheHMD controller 30 outputs the positions in the three axial directionsand the angles about the axes to the controller 16 as the attentionpoint information 19.

The controller 16 determines the attention point 114 or a sight linedirection D in the virtual space 110 based on the attention pointinformation 19. The method employed to determine the attention point orthe sight line direction may be a known method that corresponds to, forexample, the type of the tracking sensor 31. For example, the controller16 virtually sets a straight line that connects a left eye position to aright eye position and sets a direction that extends orthogonal to thestraight line and through the center point of the left eye position andthe right eye position as the sight line direction D. Further, thecontroller 16 can determine the intersection of the sight line directionD and an object (or background) as the attention point 114. When asensor that detects eye motion or a sensor that detects reflected lightfrom the inside of the iris is used as the tracking sensor, the sightline direction may be determined based on the eye motion or thereflected light.

The controller 16 obtains image information of an attention range 111,which is a range based on the attention point 114 or the sight linedirection D, from the image information memory 25 and outputs the imageinformation to the display 32 of the HMD 11 as the first virtual spaceimage. For example, when the direction extending from the viewpoint ofthe first user 101 toward the attention point 114 is set as the sightline direction D, the attention range 111 is a range identified by, forexample, a horizontal viewing angle α in the horizontal directioncentered about the sight line direction D and a vertical viewing angle(not shown) that is an angle in the vertical direction. The horizontalviewing angle α and the vertical viewing angle refer to rendering anglesthat generate images of the virtual space 110 and do not refer tophysical viewing angles of the first user 101. The controller 16 alsooutputs an image corresponding to the obtained image information to themain display 12.

The entire virtual space is displayed in an initial state in the firstvirtual space image displayed on the HMD 11 and the first virtual spaceimage displayed on the main display when a predetermined action is notperformed on the images. For example, the initial state is “darkness,”that is, a state in which the brightness and saturation of the images islow. The first virtual space image in the initial state displays movingobjects 115, which move in the virtual space, in a non-displayed state.In the non-displayed state, the moving objects are not displayed at allor are displayed in an unclear state and difficult to visuallyrecognize. The unclear displayed state is, for example, a state in whichthe moving object 115 is only partially displayed and not entirelydisplayed or a state in which at least one of the brightness,saturation, and hue of the moving object 115 is close to that of thebackground to obscure the moving object 115. Further, for example, thesecond user 102 is displayed in the virtual space as a character 116such as a drone or an avatar. In the present embodiment, the position ofthe character 116 is kept at a position located upward in the verticaldirection from the first user 101.

In addition, when a display range is designated by a touch operation tothe touch panel display 13 by the second user 102, the controller 16obtains the designated display range from the touch panel display 13 andstores the designated display range in the memory 17 as the designateddisplay range information 20. Further, the controller 16 outputs, to thetouch panel display 13, a designated display range 112 corresponding tothe designated display range information 20 as the second virtual spaceimage in a display mode that differs from that of the initial state ofthe first virtual space image. More specifically, the display mode is avaried state in which at least one of the brightness, saturation, andhue differs from that of the initial state. The varied state is, forexample, a state with light irradiation, that is, a state in which thebrightness is higher than that of the initial state and the saturationand hue differ from those of the initial state. The controller 16displays a moving object in the second virtual space image as beingvisually recognizable based on the object position information 21. Thisallows the second user to visually recognize the moving object on thesecond virtual space image.

Further, when the attention range 111 of the first user 101 overlapswith at least a part of the designated display range 112 designated bythe second user 102, the controller 16 displays the overlapped portionof the first virtual space image in the varied state, which differs fromthe initial state. More specifically, the overlapped portion isdisplayed in a state in which at least one of the brightness, saturationand hue differs from that of the other portion. FIG. 3 shows a state inwhich the attention range 111 includes the entire designated displayrange 112. In the first virtual space image, light is displayed as beingirradiated from the character 116 or from a light source the character116 has.

The controller 16 designates the designated display range 112, which isdesignated by the second user 102, in the virtual space 110 (firstaction) to reflect the first action on the first virtual space image.More specifically, in the first virtual space image, the controller 16sets only a moving object 115 included in a portion where the attentionrange is overlapped with the designated display range 112 (overlappedrange in virtual space) to a displayed state (visually recognizablestate) and sets a moving object 115 that exists in the other portionthat is not the overlapped portion to a non-displayed state(non-visually recognizable state). Thus, the first user 101 can visuallyrecognize a moving object 115 only when the attention range 111 isoverlapped with the designated display range 112 and the moving object115 is included in the overlapped portion.

Further, in the present embodiment, the designated display range 112designated by the second user 102, in other words, a horizontal viewingangle β of the projected range in the virtual space that generates thesecond virtual space image, is smaller than the horizontal viewing angleα of the projected range in the virtual space that generates the firstvirtual space image. That is, when the horizontal viewing angle β of thesecond virtual space image is greater than or equal to the horizontalviewing angle α of the first virtual space image, it facilitates findingof the designated display range 112 reflected on the first virtual spaceimage by the first user 101. In contrast, when the horizontal viewingangle β of the second virtual space image is smaller than the horizontalviewing angle α of the first virtual space image, it obstructs findingof the designated display range 112 reflected on the first virtual spaceimage by the first user 101. The ratio of the horizontal viewing angle βof the second virtual space image to the horizontal viewing angle α ofthe first virtual space image can be determined in correspondence with atarget game balance. In the present embodiment, the horizontal viewingangle β of the second virtual space image is set to be smaller than thehorizontal viewing angle α of the first virtual space image. Thisincreases the contribution of the second user 102 to the game and allowsthe first user 101 and the second user 102 to cooperate in order for thegame to progress.

In addition, the second user 102 can perform a predetermined touchoperation on the touch panel display 13 to stop moving a moving object115 displayed proximate to the contact position. The second user 102performs a touch-and-hold operation that keeps a finger in contact witha certain position on the screen. When the touch-and-hold operation isperformed, as the first action, the controller 16 identifies a movingobject displayed in a predetermined distance from the contact positionand stops movement (motion) of the identified moving object 115. Thatis, motion of the single moving object 115 closest to a single contactposition is stopped. For example, when five moving objects 115 exist inthe virtual space 110 and the user wants to stop their movement, theuser performs the touch-and-hold operation using five fingers (or atfive contact points).

Further, the first user 101 can perform the second action only on amoving object 115 that is visually recognizable in the designateddisplay range 112. In the present embodiment, the first user 101 shootsthe moving object 115 as the second action. When movement of the movingobject 115 is stopped by the touch operation performed by the seconduser 102, the first user 101 can easily aim at the moving object 115 andeasily performs a valid second action. More specifically, when thecontroller 16 detects an on-operation performed on the operation unit14, the controller 16 causes a beam 118 to be displayed in the firstvirtual space image and the second virtual space image in the directionof the operation unit 14 from a virtual position 117 of the operationunit 14. When the direction of the beam 118 corresponds to the positionof the moving object 115 in the virtual space, the controller 16determines that the second action has been validly performed. Morespecifically, the controller 16 determines that the moving object 115has been shot and gives points or the like to the first user 101. Thecontroller 16 does not cause the beam 118 for action to be displayed fora moving object 115 that is not included in the designated display range112. Alternatively, when the beam 118 for action is emitted toward themoving object 115 that is not included in the designated display range112, the controller 16 may determine that the action is invalid. Thecontroller 16 causes the beam 118 for action to be displayed on thedisplay 32 of the HMD 11, the main display 12, and the touch paneldisplay 13.

Views displayed on the display 32 of the HMD 11, the main display 12,and the touch panel display 13 will now be described with reference toFIGS. 4 to 8.

As shown in FIG. 4, the controller 16 generates image information torender image information of the virtual space recorded in the imageinformation memory 25 in correspondence with the designated displayrange 112 to display a second virtual space image 121. The controller 16further adjusts the generated image information in brightness,saturation, and hue for the second virtual space image 121, and outputsthe generated image information to the touch panel display 13. Even whenthe second virtual space image 121 displays the same range as the firstvirtual space image, the second virtual space image 121 differs from theinitial state of the first virtual space image in at least one ofbrightness, saturation, and hue. More specifically, the controller 16causes the entire second virtual space image 121 to be displayed with ahigh brightness as if irradiated with light. Further, the controller 16causes a moving object 115 that moves based on the object positioninformation 21 to be displayed in the second virtual space image 121.However, the moving object 115 moves randomly. Thus, when the designateddisplay range 112 is not varied, the moving object 115 that wasinitially displayed may move out of the screen. The second user 102performs, for example, a swipe operation to vary the designated displayrange 112 and shift the view and searches for the moving object 115 inorder to inform the first user 101 of the position of the moving object115.

As shown in FIG. 5, the controller 16 outputs a bird's-eye view image122 to the touch panel display 13 by obtaining image information for abird's-eye view image recorded in the image information memory 25 orrendering image information of the virtual space. The bird's-eye viewimage 122 is an image of the entire virtual space taken from above anddisplays, for example, the position of the character 116. The controller16 causes the designated display range 112 of the bird's-eye view image122 designated by the second user 102 to be displayed in a varied stateas if irradiated with light and causes the other portion to be displayedin the initial state such as in darkness. Further, the controller 16causes the moving object 115 to be displayed in the bird's-eye viewimage 122.

As shown in FIG. 6, when the second user 102 performs a touch-and-holdoperation in the second virtual space image 121 displayed on the touchpanel display 13, the controller 16 identifies a moving object 115displayed within a predetermined distance from the contact position of afinger and stops moving the identified moving object 115. In FIG. 6, thecontroller 16 stops movement of moving objects 115 displayed on portionswhere the relative distances from contact positions P1, P3 and P4 arewithin predetermined distances. The controller 16 cannot identify amoving object 115 displayed proximate to a contact position P2 and thusdoes not stop the moving object 115. Accordingly, the controller 16 doesnot stop moving the moving objects 115 in the right side of the drawingthat are displayed in the portion where the relative distance from acontact position P5 exceeds a predetermined distance.

As shown in FIG. 7, the controller 16 outputs a first virtual spaceimage 120 to the display 32 of the HMD 11 and changes the display rangein correspondence with the posture of the first user 101. When thecontroller 16 determines that the attention range 111 of the first user101 is overlapped with the designated display range 112 designated bythe second user 102, the controller 16 causes the overlapped portion 125of the attention range 111 and the designated display range 112 to bedisplayed in the varied state as if irradiated with light. Further, thecontroller 16 causes the other portion of the first virtual space image120 that is not the overlapped portion 125 to be displayed in theinitial state such as in darkness. In addition, when the moving objects115 are included in the overlapped portion 125, the controller 16 causesonly the moving objects 115 included in the overlapped portion 125 to bedisplayed and does not cause moving objects 115 that are not included inthe overlapped portion 125 to be displayed.

As shown in FIG. 8, when a signal corresponding to an on-operation isinput from the operation unit 14, the controller 16 reflects the secondaction on the first virtual space image 120 and outputs the firstvirtual space image 120 reflecting the second action to the display 32of the HMD 11. For example, based on a signal that detects the directionof the operation unit 14 output from the operation unit 14, thecontroller 16 causes the beam 118 to be displayed from the virtualposition 117 of the operation unit 14 in the virtual space in thedirection of the operation unit 14. When a moving object 115 exists inthe direction of the beam 118, the controller 16 validates shooting,which is the second action. Though, as described above, a moving object115 can easily be aimed at when the movement of the moving object 115 isstopped, a moving object 115 can be shot at when the movement of themoving object 115 has not been stopped. Further, for example, thecontroller 16 calculates points corresponding to the number of times avalid action is performed in a limited time and adds the points to pointinformation included in the game management information 18.

The procedures of processes for providing a game to the first user 101and the second user 102 will now be described with reference to FIGS. 9and 10.

First, the procedures of a process for outputting the first virtualspace image 120 to the HMD 11 and the main display 12 will be describedwith reference to FIG. 9. The process for outputting the first virtualspace image 120 starts when a starting condition is satisfied, forexample, when the operation unit 14 or other devices are operated tostart the game. In parallel to this process, the controller 16 executesa process for obtaining the coordinates of the designated display range112 of the touch panel display 13 and recording the coordinates in thememory 17 as the designated display range information 20.

The controller 16 obtains the attention point information 19 recorded inthe memory 17 (step S1). The controller 16 identifies the attentionrange 111 based on the attention point information 19. Further, thecontroller 16 obtains the designated display range information 20recorded in the memory 17 (step S2). The controller 16 identifies thedesignated display range 112 based on the designated display rangeinformation 20.

When identifying the attention range 111 and the designated displayrange 112, the controller 16 determines whether or not the attentionrange 111 is overlapped with the designated display range 112 (step S3).For example, the controller 16 determines whether or not the range ofthe attention range 111 in the coordinate system of the virtual space isoverlapped with the range of the designated display range 112 in thecoordinate system of the virtual space based on these ranges. Whendetermining that the attention range 111 is not overlapped with thedesignated display range 112 (step S3: NO), the controller 16 readsimage information corresponding to the attention range 111 from imageinformation recorded in the image information memory 25 and outputs thefirst virtual space image in the initial state to the display 32 of theHMD 11 and the main display 12 (step S8).

In step S3, when determining that the attention range 111 is overlappedwith the designated display range 112 (step S3: YES), the controller 16determines whether or not a moving object 115 is included in theoverlapped portion based on the object position information 21 (stepS4). When determining that the moving object 115 is not included in theoverlapped portion (step S4: NO), the controller 16 sets the overlappedportion to the varied state (step S7) and outputs the first virtualspace image to the display 32 of the HMD 11 and the main display 12(step S8). As a result, the display 32 of the HMD 11 and the maindisplay 12 display the first virtual space image 120 in which theoverlapped portion is set to the varied state and the moving object 115is set to the non-displayed state.

In step S4, when determining that the moving object 115 is included inthe overlapped portion of the attention range 111 and the designateddisplay range 112 (step S4: YES), the controller 16 sets the overlappedportion to the varied state (step S5) and sets the moving object 115included in the overlapped portion to the displayed state (step S6).Then, the controller 16 outputs the first virtual space image 120 to thedisplay 32 of the HMD 11 and the main display 12 (step S8). As a result,the display 32 of the HMD 11 and the main display 12 display the firstvirtual space image 120 in which the overlapped portion is set to thevaried state and the moving object 115 included in the overlappedportion is displayed.

In this manner, when outputting the first virtual space image 120, thecontroller 16 returns to step S1 and repeats steps S1 to S8 until thegame ends. When the operation unit 14 is on-operated, the controller 16causes the beam 118 to be displayed in the first virtual space image120. Further, when the position of the moving object 115 in thedisplayed state corresponds to the direction of the operation unit 14,the controller 16 determines that the second action has been validlyperformed.

The process for stopping movement of the moving object 115 by receivinga touch operation performed by the second user 102 will now be describedwith reference to FIG. 10. The process for stopping movement of themoving object 115 starts when a starting condition is satisfied such aswhen a touch-and-hold operation is detected by the controller 16. Inparallel to this process, the controller 16 executes a process forobtaining the coordinates of the designated display range 112 of thetouch panel display 13 and recording the coordinates as the designateddisplay range information 20 in the memory 17.

The controller 16 obtains the contact position information 22 recordedin the memory 17 and identifies the contact position (step S10).Further, the controller 16 determines whether or not at least one of thedisplayed moving objects 115 has been identified proximate to thecontact position (step S11). More specifically, the controller 16identifies the position of the displayed moving object 115 based on theobject position information 21. Then, the controller 16 calculates therelative distance from the identified contact position and the positionof the moving object 115 and determines whether or not the relativedistance from the moving object 115 is within a predetermined distance.

When the controller 16 determines that there is no moving object 115where the relative distance from the contact position is within thepredetermined distance (step S11: NO), the controller 16 ends theprocess without stopping movement of any moving object 115. Further,when the controller 16 determines that there is at least one movingobject 115 where the relative distance from the contact position iswithin the predetermined distance (step S11: YES), the controller 16stops moving the identified moving object (step S12).

When stopping movement of the identified moving object 115, thecontroller 16 determines whether or not the finger of the second user102 has been released from the screen of the touch panel display 13(step S13). When determining that the finger of the second user 102 hasnot been released (step S13: NO), the controller 16 continues stoppingmovement of the identified moving object 115 (step S12). Whendetermining that the finger of the second user 102 has been released(step S13: YES), the controller 16 resumes movement of the moving object115 (step S14) and ends the process of the touch-and-hold operation.When the starting condition is satisfied, the controller 16 repeats theprocesses from step S1 to step S13.

As described above, the first embodiment has the following advantages.

(1) In the above embodiment, the controller 16 of the control device 15outputs a virtual space image to both the HMD 11 and the touch paneldisplay 13. The second user 102 designates the designated display range112 by a touch operation without wearing the HMD 11, and the controller16 identifies the range corresponding to the touch operation in thevirtual space as the first action. That is, the second user 102 assiststhe first user 101 by the first action. Further, the first user 101 usesthe operation unit 14 to perform operation on a moving object 115displayed in the overlapped portion of the attention range 111 and thedesignated display range 112, and the controller 16 performs the secondaction on the moving object 115 in correspondence with the operation.Thus, the second user 102 has to perform the first action for the firstuser 101 to perform the second action. This allows the first user 101and the second user 102 to cooperate in the virtual space in order forthe game to progress.

(2) In the above embodiment, the controller 16 identifies the designateddisplay range 112 designated by the second user 102. Then, thecontroller 16 reflects the designated display range 112 on the firstvirtual space image 120. Thus, the second user 102 can point out acertain range in the virtual space to the first user 101 without wearingthe HMD 11.

(3) In the above embodiment, when the designated display range 112 isnot overlapped with the attention range 111, the controller 16 outputs amoving object 115 in a non-displayed state to the HMD 11. When thedesignated display range 112 is overlapped with the attention range 111,the controller 16 outputs the moving object 115 included in theoverlapped portion to the HMD 11 in a displayed state. That is, thesecond user 102 designates a certain range including the moving object115, and the first user 101 includes the designated range in theattention range 111. This allows the first user to visually recognizethe moving object 115. Accordingly, the first user 101 and the seconduser 102 can cooperate in order for the game to progress.

(4) In the above embodiment, the controller 16 outputs the first virtualspace image to the HMD 11 where at least one of brightness, saturation,and hue of the designated display range 112 differs from that of theother range of the designated display range 112. This allows the firstuser 101 who is wearing the HMD 11 to distinguish the range designatedwith the touch panel display 13 from the other range. Further, thecontroller 16 causes the range designated by the second user 102 withthe touch panel display 13 to be displayed as if irradiated with light.This limits decreases in the sense of immersion of the first user 101 ascompared to when, for example, the range is indicated to the first user101 by a line enclosing the range.

(5) In the above embodiment, the controller 16 validates the secondaction only for the moving object 115 that is included in the overlappedportion of the attention range 111 and the designated display range 112.Thus, in order to validly perform the second action, the moving object115 has to be included in the designated display range 112 designated bythe second user 102. Accordingly, the first user 101 and the second user102 can cooperate in order for the game to progress.

(6) In the above embodiment, the controller 16 sets the horizontalviewing angle β of the second virtual space image 121 to be smaller thanthe horizontal viewing angle α of the first virtual space image 120.Thus, the first user 101 needs to perform operations for the secondaction within a narrow range in the virtual space. This increases thedifficulty of the second action and requires assistance of the seconduser 102. Accordingly, the first user 101 and the second user 102 cancooperate in order for the game to progress.

(7) In the above embodiment, the controller 16 causes the touch paneldisplay 13 to constantly display a moving object 115. Thus, in order forthe first user 101 to find the moving object 115, the second user 102has to provide the position information of the moving object 115 bydesignating the designated display range 112. That is, the first user101 is supposed to search for the moving object 115 based on theposition information of the moving object 115 provided from the seconduser 102. Accordingly, the first user 101 and the second user 102 cancooperate in order for the game to progress. (8) In the aboveembodiment, the controller 16 moves a moving object 115 in the firstvirtual space image 120 output to the HMD 11. Further, as the firstaction, the controller 16 stops moving the moving object 115 in thefirst virtual space image 120 and the second virtual space image 121output to the touch panel display 13 based on a touch operationperformed on the touch panel display 13. This allows the first user 101to easily shoot, which is the second action, the moving object 115 ofwhich movement has been stopped. Accordingly, the first user 101 and thesecond user 102 can cooperate in order for the game to progress.

(9) In the above embodiment, the controller 16 identifies a movingobject 115 displayed proximate to a contact point on the screen of thetouch panel display 13 and stops moving only the identified movingobject 115. That is, movement of a single moving object 115 can bestopped with a single contact point. The second user 102 only needs totouch the vicinity of a portion on the screen that displays a movingobject 115, the movement of which the second user 102 wants to stop.This facilitates intuitive understanding by the second user 102 of theoperation for stopping the movement. Further, when stopping movement ofmultiple moving objects 115, it requires contact points, the number ofwhich is equal to that of the moving objects 115. This can increase thedifficulty for stopping moving objects in correspondence with the numberof the moving objects 115, the movement of which the second user 102wants to stop.

(10) In the above embodiment, the controller 16 sets the moving object115 to a displayed state and outputs the bird's-eye view image 122,which is a bird's-eye view of the virtual space, to the touch paneldisplay 13. This allows the second user 102 to understand the positionor state of the moving object 115 included in the virtual space. Thus,the moving object 115 that is aimed to shoot, which is the secondaction, is easily included in the designated display range 112. Further,the second user 102 easily understands the positional relationship ofthe designated display range 112 and the moving object 115.

Second Embodiment

A second embodiment of the present invention will now be described. Inthe second embodiment, the first action of the first embodiment ismodified. Like or same reference numerals are given to those componentsthat are the same as the corresponding components of the firstembodiment. Such components will not be described in detail.

In the first embodiment, the first action is to identify the designateddisplay range 112. In the present embodiment, the first action is toselect a moving object 115 based on operation performed by the seconduser 102. In the present embodiment, in the initial state of the firstvirtual space image 120 output to the HMD 11, at least moving objects115 only need to be in a non-displayed state. That is, the first virtualspace image 120 of the present embodiment does not have to be in adisplayed state having a low brightness such as a state of “darkness.”

As shown in FIG. 11, the second virtual space image 121 displayed on thetouch panel display 13 displays the moving objects 115. The second user102 designates a moving object 115 by a touch operation. FIG. 11displays an example in which there is one contact position P10. However,there may be multiple contact positions.

The controller 16 obtains the coordinates of the contact position P10from the touch panel display 13. Then, based on the object positioninformation 21, the controller 16 determines whether or not there is amoving object 115 displayed in a portion where the relative distancefrom the coordinates of the contact position P10 is less than or equalto a predetermined distance.

When the controller 16 determines that there is a moving object 115displayed in the portion where the relative distance from the contactposition P10 is less than or equal to the predetermined distance, thecontroller 16 sets the moving object 115 to a displayed state on thefirst virtual space image 120 and outputs the moving object 115 to thedisplay 32 of the HMD 11 and the main display 12. Although the firstembodiment executes a process for stopping movement of a moving object115 displayed proximate to the contact position P10, the secondembodiment does not execute the process.

As long as the relative distance from the contact position P10 and themoving object 115 remains less than or equal to the predetermineddistance, the controller 16 continues to display the moving object 115on the first virtual space image. When the relative distance from thecontact position P10 and the moving object 115 exceeds the predetermineddistance as the moving object 115 moves even if the second user 102 iscontinuing the touch operation, the controller 16 sets the moving object115 to the non-displayed state.

In this manner, in the present embodiment, a moving object 115 selectedby the second user 102 is displayed in the first virtual space image120. Thus, the task for designating a moving object 115 becomes furthercomplex. As a result, the first user 101 and the second user 102 need tocooperate closely. This increases the degree of amusement with apreferred difficulty of the game.

As described above, the second embodiment has the following advantage inaddition to advantage (1) of the first embodiment.

(11) In the above embodiment, the controller 16 of the control device 15identifies a moving object 115 selected by the second user 102. Then,the controller 16 causes the moving object 115 selected by the seconduser 102 to be displayed in the first virtual space image 120. Thus, thesecond user 102 can point out the selected moving object 115 to thefirst user 101 without wearing the HMD 11.

Third Embodiment

A third embodiment of the present invention will now be described. Inthe third embodiment, the designated display range of the firstembodiment is variable. Like or same reference numerals are given tothose components that are the same as the corresponding components ofthe first embodiment. Such components will not be described in detail.

In the first embodiment, the designated display range 112 is the entirerange displayed in the touch panel display 13 by a touch operation ofthe second user 102. In the present embodiment, the size or position ofthe designated display range 112 can be varied by a touch operationperformed by the second user 102.

As shown in FIG. 12, the second user 102 varies the size or position ofthe designated display range 112 by, for example, a pinch-in operationwhere the second user 102 moves two fingers toward each other on thescreen or a pinch-out operation where the second user 102 moves twofingers away from each other on the screen. The designated display range112 is the entire screen in the initial state. When the pinch-inoperation is performed, the controller 16 contracts the designateddisplay range 112 based on the path of the pinch-in operation. When thepinch-out operation is performed, the controller 16 enlarges thecontracted designated display range 112 based on the path of thepinch-out operation. Further, when the two fingers move in contact withthe screen after the pinch-in operation or the pinch-out operation, thecontroller 16 moves the designated display range 112 in the view basedon the input path of the operation while maintaining the size of thedesignated display range 112. The position of the light source (origin)may be moved in accordance with the movement of the designated displayrange 112.

In addition, contraction of the designated display range 112 may producea special effect on the moving objects 115. For example, moving objects115 included in the designated display range 112 at the point of timewhen contraction of the designated display range 112 starts may berestricted from moving out of the designated display range 112. As aresult, contraction of the designated display range 112 can gather themoving objects 115, which are included in the designated display range112, in the contracted designated display range 112. When the movingobjects 115 are gathered in such a narrow range, the first user 101 caneasily shoot a large number of moving objects 115 at the same time.

When the pinch-in operation is performed, based on the input path of thetouch operation, the controller 16 contracts the designated displayrange 112 in correspondence with the length or angle of the input path.Further, the controller 16 outputs, to the touch panel display 13, thesecond virtual space image 121 in a varied state in which thebrightness, saturation, and hue of the contracted designated displayrange 112 differ from those of the other range. The second virtual spaceimage 121 includes a portion in the initial state, for example, in“darkness,” displayed with a low brightness and saturation. Thecontroller 16 may set moving objects 115 included in the portion of theinitial state to a displayed state or a non-displayed state.

In addition, the controller 16 determines whether or not there is aportion where the attention range 111 and the designated display range112 of the first user 101 are overlapped. When the overlapped portionexists, the controller 16 outputs, to the display 32 of the HMD 11 andthe main display 12, the first virtual space image 120 in which theoverlapped portion is set to the varied state and the other portion isset to the initial state.

When the first user 101 validly performs shooting or the like, themoving objects 115 included in the designated display range 112 areeliminated or reduced in number. Then, the second user 102 performs thepinch-out operation for enlarging the designated display range 112 onthe screen of the touch panel display 13. When the pinch-out operationis performed, the controller 16 enlarges the designated display range112 in correspondence with the length or angle of the input path of aninput touch operation. Further, the controller 16 outputs, to the touchpanel display 13, the second virtual space image 121 in which theenlarged designated display range 112 is set to the varied state and theother portion is set to the initial state. Thus, the designated displayrange 112 will include new moving objects 115.

As described above, the third embodiment has the following advantage inaddition to advantages (1) to (10) of the first embodiment.

(12) In the above embodiment, the controller 16 varies the size orposition of the designated display range 112 based on the touchoperation performed on the screen of the touch panel display 13. Thisallows for, for example, only part of the view to be pointed out.

Fourth Embodiment

A fourth embodiment of the present invention will now be described. Inthe fourth embodiment, a moving object is set to a non-displayed statewith the touch panel display and displayed in the second virtual spaceimage in correspondence with operation performed on the operation unit.Like or same reference numerals are given to those components that arethe same as the corresponding components of the first embodiment. Suchcomponents will not be described in detail.

In the first embodiment, the first action is to identify the designateddisplay range 112 based on operation performed by the second user 102,and the second action is to shoot a moving object 115 based on operationperformed by the first user. In the present embodiment, the first actionis to select a moving object 115 by the first user 101, and the secondaction is to attack a moving object 115 based on a touch operationperformed by the second user 102 on the touch panel display 13.

As shown in FIG. 13, the controller 16 outputs, to the display 32 of theHMD 11 and the main display 12, the first virtual space image 120 inwhich moving objects 115 are constantly in displayed states. Theoperation unit 14 operated by the first user 101 is a controller or aglove controller that can vary directions and be on- and off-operated.The first user 101 operates the operation unit 14 to select a movingobject 115 in the virtual space. More specifically, the controller 16varies the orientation of a light source 130 such as a flashlightdisplayed in the first virtual space image 120 depending on theoperation performed on the operation unit 14. This allows a movingobject 115 to be irradiated with light and to be selected.Alternatively, a moving object 115 is captured using a tool such as anet or case in the virtual space.

A signal output from the operation unit 14 is input to the controller16, and the controller 16 determines whether or not a moving object 115has been selected based on the object position information 21. Whendetermining that the moving object 115 has been selected, the controller16 outputs, to the touch panel display 13, the second virtual spaceimage 121 in which the selected moving object 115 is set to a displayedstate.

In the initial state, a moving object 115 is set to a non-displayedstate in the second virtual space image 121 output to the touch paneldisplay 13. When the moving object 115 selected by the first user 101 isset to the displayed state on the second virtual space image 121, thesecond user performs a touch operation on the moving object 115, whichis in the displayed state, to attack the moving object 115. When thecontroller 16 determines that the moving object 115 has been attackedbased on a signal input from the touch panel display 13, the controller16 reflects the attack to the moving object 115 on the first virtualspace image 120 and outputs the first virtual space image 120 to the HMD11 and the main display 12.

As described above, the fourth embodiment has the following advantage.

(13) In the above embodiment, the first user 101 selects a moving object115 and sets the selected moving object 115 to a displayed state on thesecond virtual space image 121. The second user 102 can attack themoving object 115, which is in the displayed state in the virtual space,without wearing the HMD 11. This allows the first user 101 and thesecond user 102 to cooperate in order for the game to progress.

Other Embodiments

Each of the above embodiments may be modified as described below.

In each of the above embodiments, the controller 16 sets the position ofthe character 116, which corresponds to the second user 102 in thevirtual space, to a position located upward in the vertical directionfrom the first user 101. Instead, the position of the character 116 maybe changed based on, for example, a touch operation performed by thesecond user 102 on the screen of the touch panel display 13.

In each of the above embodiments, the horizontal viewing angle β of thesecond virtual space image is smaller than the horizontal viewing angleα of the first virtual space image. Instead, the horizontal viewingangle β of the second virtual space image may be equal to or larger thanthe horizontal viewing angle α of the first virtual space image 120.This facilitates finding in the designated display range 112. Thus, thisis effective for, for example, reducing the difficulty in finding anobject. In the same manner, the vertical viewing angle of the secondvirtual space image may be smaller than the vertical viewing angle ofthe second virtual space image or greater than or equal to the verticalviewing angle of the second virtual space image.

In each of the above embodiments, the controller 16 causes the maindisplay 12 to display the attention range of the first user 101 as thefirst virtual space image. Alternatively or additionally, the controller16 may cause the attention range 111 of the first user 101 to bedisplayed on, for example, the second virtual space image 121. Theattention range 111 may be indicated by enclosing the range with a line.The attention range 111 may be displayed so that at least one of thebrightness, saturation, and hue of the attention range 111 differs fromthat of the background of the second virtual space image 121. In thiscase, the main display 12, which the second user 102 visuallyrecognizes, may be omitted.

In each of the above embodiments, the controller 16 outputs thebird's-eye view image 122 that is a bird's eye view of the virtual spaceto the touch panel display 13. However, when, for example, the objectpositions in the virtual space are easy to understand, the bird's-eyeview image 122 does not have to be displayed.

In each of the above embodiments, the controller 16 causes at least oneof the brightness, saturation, and hue of the designated display range112 to be displayed differently from the portion other than thedesignated display range 112. In addition, as the first action, thedesignated display range 112 may be enclosed by a line displayed in theimage or be marked with an arrow or the like.

In each of the above embodiments, the controller 16 causes thedesignated display range 112 to be displayed on the first virtual spaceimage and the second virtual space image where at least one of thebrightness, saturation, and hue of the designated display range 112differs from that of the portion other than the designated display range112. In addition, as time elapses, the controller 16 may cause thedesignated display range 112 to be displayed changing at least one ofthe brightness, saturation, and hue as time elapses. More specifically,when the designated display range 112 is displayed in brightness,saturation, and hue as if irradiated with light, the controller 16 may,as time elapses, vary at least one of the brightness, saturation, andhue so as to darken the designated display range 112 or irradiate thedesignated display range 112 with light of a color differing from thelight in the initial state.

In each of the above embodiments, the controller 16 stops moving amoving object 115 as the first action based on the contact position ofthe second user 102 on the touch panel display 13. Alternatively oradditionally, the controller 16 may stop moving a moving object 115based on a selection operation performed on an item displayed in theview on the touch panel display 13. For example, when a special itemdisplayed in the view of the touch panel display 13 is selected, thecontroller 16 may stop moving all of the moving objects 115 displayed inthe view of the touch panel display 13. Further, when the item isdragged and dropped to the vicinity of a portion in the screen thatdisplays a moving object 115, the controller 16 may stop moving themoving object 115.

In each of the above embodiments, the controller 16 stops moving amoving object 115 as the first action based on the contact position ofthe second user 102 on the touch panel display 13. Alternatively oradditionally, the controller 16 may stop moving a moving object includedin a predetermined range corresponding to a single contact position. Thepredetermined range corresponding to the single contact position is, forexample, a circular range centered about the contact position or arectangular or sectoral range where the contact position is set to astarting point (for example, corner). As another option, thepredetermined range may be selected by swiping, tapping with twofingers, or the like.

In each of the above embodiments, the second action is performed on amoving object 115 that is constantly moving. Alternatively oradditionally, the second action may be performed on an object arrangedat a predetermined fixed position in the virtual space. Such an objectis, for example, a box, a door, a musical instrument, or the likearranged in the virtual space. In this case, the second action is, forexample, to open a box lid, open a door, play the musical instrument, orthe like.

In each of the above embodiments, the second action cannot be performedor is invalidated when performed on a moving object 115 that is notincluded in the overlapped portion of the attention range 111 and thedesignated display range 112. Instead, the second action may beperformed on an object that is not included in the overlapped portion.In this case, for example, an object included in the overlapped portionmay be clearly displayed so that the object can easily be aimed at, andan object that is not included in the overlapped portion may beunclearly displayed. Further, when a valid action is performed on anobject that is not included in the overlapped portion, higher points maybe obtained as compared to when a valid action is performed on an objectincluded in the overlapped portion.

In each of the above embodiments, a predetermined object (moving object115) is in a non-displayed state in the first virtual space image outputto the display 32 of the HMD 11 and the main display 12. Instead, anobject that is subject to the second action may be in a displayed statein the first virtual space image. In this case, for example, the displaymode of the overlapped portion of the attention range 111 and thedesignated display range 112 may differ from that of the other portionso that the second action is valid only for a moving object 115 includedin the overlapped portion. Even in this case, the second action isvalidated only for the predetermined object included in the overlappedportion. This allows the first user 101 and the second user 102 tocooperate in order for the game to progress.

Instead, the display mode of an object or a virtual space image of theobject may be different between the first virtual space image and thesecond virtual space image. For example, the second virtual space imagecan be enlarged or contracted, and the second virtual space image candisplay an object at any angle. However, the first virtual space imagecannot be enlarged or contracted or can display an object only at acertain angle. Alternatively, the second virtual space image may be abird's-eye view image that is a bird's-eye view of the virtual spaceincluding an object, and the first virtual space image may display nobird's-eye view image. As another option, a predetermined imageprocessing such as transmission or edge extraction performed on thesecond virtual space image may be enabled, and a predetermined imageprocessing performed on the first virtual space image may be disabled.

FIGS. 14 and 15 show an example in which the second virtual space imageis a bird's-eye view image that is a bird's-eye view of the virtualspace including an object and the first virtual space image is not abird's-eye view image. For example, the game played by the first user101 and the second user 102 is a puzzle game in which three-dimensionalfigures are combined. As shown in FIG. 14, the controller 16 outputs, tothe HMD 11 or the like, the first virtual space image 120 that is animage of a virtual space including a three-dimensional FIG. 150, whichis an object, in correspondence with the posture of the first user 101.The three-dimensional FIG. 150 may be, for example, a triangular prism,a circular cone, or a sphere in addition to a cube and a cuboid and isnot particularly limited. The first user 101 operates the operation unit14 to combine the three-dimensional figures. When a predetermined numberor more of three-dimensional FIGS. 150 are combined, it is difficult toinclude, in a viewing angle of the first virtual space image 120, theentire pattern formed by a combination of the three-dimensional FIGS.150. Thus, when the first user 101 forms a targeted pattern, it isdifficult to determine positions where the three-dimensional FIGS. 150should be located and/or the types of the three-dimensional FIGS. 150that should be arranged.

As shown in FIG. 15, the controller 16 outputs, to the touch paneldisplay 13, the bird's-eye view image 122 that is a bird's-eye view ofthe pattern formed by a combination of three-dimensional FIGS. 150. Thesecond user 102 can visually recognize the entire pattern through thebird's-eye view image 122 and thus easily determine on which positionsthe three-dimensional FIGS. 150 should be arranged.

Further, when, for example, the second user 102 touches a predeterminedposition on the screen of the touch panel display 13 as shown in FIG.15, the controller 16 uses an instruction position mark 151 to displaythe position where a three-dimensional FIG. 150 should be arranged inthe first virtual space image 120 (first action) as shown in FIG. 14.Alternatively, instead of the instruction position mark 151, theposition where a three-dimensional FIG. 150 should be arranged may bedisplayed in a display mode that differs from a display mode of theother portion. The controller 16 arranges a three-dimensional FIG. 150at a position that is based on operation performed by the first user 101on the operation unit 14 (second action).

Further, in a puzzle game in which an action is performed based on thelayout of the types of the three-dimensional FIGS. 150, for example, thesecond user 102 selects a three-dimensional FIG. 150 from a displayregion 153 for selecting the types of the three-dimensional FIGS. 150and touches the position where the three-dimensional FIG. 150 should bearranged (refer to FIG. 15). As shown in FIG. 14, the controller 16 usesa type identification mark 152 to display the type of athree-dimensional FIG. 150 that should be arranged (first action).Additionally, the position where the three-dimensional FIG. 150 shouldbe arranged may be displayed using the instruction position mark 151 orthe like. The first user 101 operates the operation unit 14 to arrangethe three-dimensional FIG. 150 indicated by the type identification mark152 at the position indicated by the instruction position mark 151.

In each of the above embodiments, as the first action, the range of theinside of the virtual space is designated as the designated displayrange 112 based on a touch operation performed on the touch paneldisplay 13. Instead, as the first action, the direction or the positioninside the virtual space may be indicated based on the touch operationperformed on the touch panel display 13.

FIGS. 16A and 16B show an example view output in a maze game. As shownin FIG. 16A, the controller 16 causes the display 32 of the HMD 11 orthe like to display an image of a three-dimensional maze 160 arranged inthe virtual space as the first virtual space image 120. The controller16 outputs the first virtual space image 120 in correspondence with theposture of the user and varies the first virtual space image 120 so asto advance through the three-dimensional maze 160 based on operationperformed on the operation unit 14 or a user position detected by asensor. As shown in FIG. 16B, the controller 16 causes the touch paneldisplay 13 to display a bird's-eye view image of the three-dimensionalmaze 160 as the second virtual space image 121. The controller 16 causesa position 161 of the first user 101 to be displayed in the secondvirtual space image 121. As the first user 101 advances, the second user102, for example, moves a finger in the direction in which the firstuser 101 should further advance while visually recognizing the secondvirtual space image 121. The controller 16 obtains the input pathcorresponding to the touch operation from the touch panel display 13 anddisplays the instructed direction along the input path (first action) inthe first virtual space image 120. For example, the direction instructedby the second user 102 may be displayed in the first virtual space image120 as light having brightness, saturation, and hue that differs fromthose of the background or may be displayed on the first virtual spaceimage 120 as an indicator such as an arrow. The first user 101 advancesthrough the three-dimensional maze 160 by operating the operation unit14 or the like with reference to the direction instructed on the firstvirtual space image 120.

Each of the above embodiments may include a position detection sensorthat detects the position of the first user 101 in real space inaddition to the HMD 11, which detects the position and orientation ofthe head of the first user 101. Using the position detection sensor, thecontroller 16 detects the position where the first user 101 is standingas well as the position and orientation of the head of the first user101 and renders image information of the virtual space in correspondencewith the position where the first user 101 is standing to display thefirst virtual space image. As a result, the first virtual space imagevaries as the first user 101 moves. This further increases the sense ofimmersion.

In each of the above embodiments, the touch panel display 13 is used asthe operation unit for which the second user 102 can provide inputs.Instead, an operation unit 230 including no display may be used. Asshown in FIG. 17, the application control system includes an operationunit 230 (first operation unit) including a switch and the like. Thesecond user 102 operates the operation unit 230 while visuallyrecognizing an image displayed on the main display 12, and thecontroller 16 performs the first action in the virtual space incorrespondence with an input operation performed by the second user 102on the operation unit 230.

FIG. 18 shows one example of the configuration of the control device 15.The control device 15 includes a CPU 201, a ROM 202, and a RAM 203 ascontrollers. The CPU 201, the ROM 202, and the RAM 203 are connected toone another by various buses 204. Further, the control device 15includes a storage device 207 as the memory 17 and the image informationmemory 25. The CPU 201 outputs image information to the main display 12and the HMD 11 via an interface 205. Referring to FIG. 18, the CPU 201may obtain an operation signal from the operation unit 14 (secondoperation unit), which is operated by the first user 101, via the HMD 11or may obtain an operation signal from the operation unit 14 withoutusing the HMD 11. In addition, the CPU 201 obtains an operation signalfrom the operation unit 230, which is operated by the second user 102,via the interface 205. The control device 15 and the operation unit 230may be connected by a communication cable or may be connected viawireless communication. This aspect eliminates the need for the seconduser 102 to compare an image displayed on the main display 12 with animage displayed on the touch panel display 13.

In each of the above embodiments, the game in which a virtual spaceimage is output to the HMD 11 and the touch panel display 13 is embodiedin a game of shooting a predetermined object. Instead, the game in whicha virtual space image is output to the HMD 11 and the touch paneldisplay 13 may be applied to other games such as an exploration game, acard game, a racing game, a fighting game, a simulation game, and aroll-playing game. Further, the action performed on an object is notlimited to “shooting” and may be other actions such as deforming,throwing, hitting, splitting, scattering, rotating, and moving.

In each of the above embodiments, the application in which a virtualspace image is output to the HMD 11 and the touch panel display 13 isembodied in a game. Instead, the application may be an application otherthan a game, for example, an application that performs simulations usedfor fields other than game fields such as medical fields and educationalfields and an application in which training is performed.
